This is basically one of the best DS games i have EVER played. Westerners like to whine about all the reading - this game is a VISUAL NOVEL/puzzle game. I hate seeing reviews where they act like this is some sort of downfall to the game. It's like playing a fighting game and complaining that there's too much fighting. You should know what you're getting into when you start playing a VISUAL NOVEL.
Anywho, as such, this is one of the best written and applied, not to mention the puzzles and characters are fantastic. You pretty much have to complete all the endings to get the full story, but after you start playing, believe me, you'll WANT to. Wonderful mind-screw as well.
I SO urge everyone to get this one.
